Arthur Daniels

Arthur Daniels, 51, of Southeast Washington D.C., "was a good father and a hard worker," his wife, Priscilla Daniels, told the Washington Post.

A father of five and a grandfather of nine, Daniels installed office furniture in federal government buildings in the Washington D.C. region, according to the Washington Post. On Monday, he was working inside the Navy Yard when shots rang out.

Witnesses told the Washington Post that Daniels tried to flee Building 197 when spotted by a gunman running down a hallway. But as he pushed the elevator button in attempts of escaping, he was shot in the back.

"It was totally surreal," said the witness, who worked with Daniels.

Daniels, who was a subcontractor for the District Furniture Repair Company in Arlington County, "always helping others," Lewis R. Yancey II, the company's owner, told the Washington Post.

Daniels' son, Arthur Jr., said his family was shaken by news.

"All he did was go to work," he said. "That was his only crime."

Michael Arnold

Michael Arnold, 59, of Lorton, Va., was an avid pilot who was building a light airplane in his home, his uncle Steve Hunter, told the Associated Press.

"It would have been the first plane he ever owned," Hunter told the AP. "It's partially assembled in his basement."

Arnold had been married to his wife, Jolanda, for more than 30 years, Hunter said. The couple had two sons, Eric and Christopher.

"He was a loving son of his mother and his wife, and great father to his kids," said Hunter. "It's tragic. How can you get up in the morning and go to work and have that happen? How do bad things like that happen to good people?"

Arnold had recently joined the government consulting firm LMI after serving in the Navy for 29 years, Hunter said.
